Judging by its massive, bone-crushing teeth, gigantic skull and potent jaw, there is no doubt that the Anteosaurus, a premammalian reptile that roamed the African continent 265 to 260 million yrs back – all through a time period recognised as the middle Permian – was a ferocious carnivore.
Nevertheless, though it was formerly considered that this beast of a creature – that grew to about the size of an grownup hippo or rhino, and that includes a thick crocodilian tail – was also weighty and sluggish to be an efficient hunter, a new review has demonstrated that the Anteosaurus would have been equipped to outrun, keep track of down and destroy its prey correctly.
Even with its title and intense visual appeal, Anteosaurus is not a dinosaur but fairly belongs to the dinocephalians–mammal-like reptiles predating the dinosaurs. Much like the dinosaurs, dinocephalians roamed and ruled the Earth in the earlier, but they originated, thrived, and died about 30 million several years just before the 1st dinosaur even existed.
The fossilised bones of Dinocephalians are uncovered in lots of spots in the world. They stand out by their substantial size and significant pounds. Dinocephalian bones are thick and dense, and Anteosaurus is no exception. The Anteosaurus’ cranium was ornamented with substantial bosses (bumps and lumps) higher than the eyes and a extensive crest on top rated of the snout which, in addition to its enlarged canines, built its skull appear like that of a ferocious creature. Even so, since of the large architecture of its skeleton, it was previously assumed that it was a alternatively sluggish, gradual-transferring animal, only capable of scavenging or ambushing its prey, at finest. 
“Some scientists even prompt that Anteosaurus was so major that it could only have lived in drinking water,” claims Dr Julien Benoit of the Evolutionary Reports Institute at the University of the Witwatersrand (Wits University).
By carefully reconstructing the skull of the Anteosaurus digitally using X-ray imaging and 3D reconstructions, a team of researchers investigated the inside structures of the cranium and uncovered that the certain features of its mind and harmony organs were being made in such a way that it was almost everything but gradual-shifting. 
“Agile predators these types of as cheetahs or the infamous Velociraptor have normally experienced a very specialised nervous techniques and high-quality-tuned sensory organs that enable them to monitor and hunt down prey effectively,” states Benoit. “We wished to locate out no matter whether the Anteosaurus possessed identical variations.”
The team identified that the organ of harmony in Anteosaurus (its interior ear) was reasonably larger than that of its closest relations and other contemporaneous predators. This signifies that Anteosaurus was capable of relocating a great deal more quickly than its prey and rivals. They also discovered that the component of the brain responsible for coordinating the movements of the eyes with the head was extremely significant, which would have been a very important trait to make sure the animal’s tracking capabilities.
“In building the most entire reconstruction of an Anteosaurus cranium to day, we found that general, the anxious program of Anteosaurus was optimised and specialised for hunting quickly and hanging rapid, compared with what was previously thought,” states Dr Ashley Kruger from the All-natural Heritage Museum in Stockholm, Sweden and formerly from Wits College. 
“Even although Anteosaurus lived 200-million decades in advance of the famous dinosaur Tyrannosaurus rex, Anteosaurus was definitely not a ‘primitive’ creature, and was practically nothing short of a mighty prehistoric killing equipment,” says Benoit.
